SPECIFICATION forming part of Letters atent No. 727,048, dated May 5, 1903'.

Application led August 11, 1902. Serial No. 119.236. (No model.)

chine and crush the clods and lumps and pul- Iremoved from the near side thereof.

verize the soil preliminary to its engagement by the cultivating appliances; and my object is to produce a machine of this characterof simple, strong, durable, and inexpensive oo nstruction and which having but few adjustable parts is easy to operate and not liable to get out of order.

Referring to the accompanying drawings, Figure l represents a perspective view of my improved cultivator with the disks and shaft Fig. 2 is a detail cross-sectional view of the runners and shaft with rollers journaled on the latter.

In constructing myimproved machine I employ a pair of runners 1, adapted to carry the.

machine when on the road and to guide it over the rows in the field by traveling along in the furrows. Rigidly secured near the central top portion of the runners with cleats 2 are bearing-blocks 3, having broad bases 4 resting on the runners. Said bearing-blocks taper toward their upper ends ,and carry a stationary transverse shaft 5, arched at its central port-ion 5 to clear the plants under cultivation and also to provide a support for the drivers seat 7. The opposite end portions of the transverse shaft extend outwardly beyond the bearing-blocks to receive cylindrical rollers 6, journaled thereon and arranged at such height as to practically carry all the weight of the machine when traveling over the ridges in the field, and thereby serve to crush clods and lumps, pulverize the soil in advance of the cultivating appliances, and lighten the-draft of the machine. Said rollers are held in position on the ends of the shaft by spring-cotters 8 and braces 9, secured at their opposite ends to the terminals of the shaft and a cross-bar 10 at the upper front portion of the machine. Cross-bar l0 is supported by'standards 11, secured at their lower ends to the front portions of the runners and provided near theircentral portions with footrests 12 for the convenience of the driver. The standards also have perforations l2a to adjustably receive links 13, to which the draftrods 14. are hooked.

15 indicates a brace extending from the central portion of the cross-bar to the arch 4 of the transverse shaftv to rigidly secure said arched portion in an upright position and provide a'stable support for the drivers seat.

The rear portions of the runners are provided with boxes 16y to receive a journaled shaft 17, having a central arch 18 to clear the plants under cultivation. Said shaft is o perated by a hand-lever 19, arranged within convenient reach of the driver and provided with a spring-latch 20, adapted to engage a notched segment 21 on the cap'of one of the boxes 16 for the purpose of locking said shaf t at any point of its adjustment. The opposite terminals of shaft 17 extend outwardly a suitable distance from the boxes to receive arms 22, adjustably carrying at their rear ends shafts 23, provided with' a plurality of disks 24. i

Arms 22 arelatera'll y adjustable upon shafts 17 in order that the disks or other cultivating appliances employed maybe made to follow in the path of the rollers, and thereby increase their elfectiveness by operating on soil free from lumps and-clods.

During the rst cultivation of the corn the young plants are protected from being covered with earthby a fender 25, formed into an arch and provided at its forward opposite sides with arms pivotally secured tothe rear portions of the runners with bolts 27.A Said fender is simultaneously raised and lowered with the cultivating appliances byvmeans of a chain 28', attached at its opposite ends to hooks 29 30, respectively, on arch'18 and the rear end of the fender.

Having thus described my invention, what I claim,and desire to secure by Letters Pat` ent, is-v 4 l. A cultivator comprising a pair of' runners,bearings secured thereon,an arched shaft carried by the bearings and provided with a seat, cylindrical rollers journaled upon the opposite sides of the shaft at a suitable distance above the runners, bearings upon the ICO rear portions of the runners, a shaft join'- naled therein, a hand-lever for operating the shaft, and disks suitably secured vto the oppesite sides of the shaft, substantially as shown and described.

2. A cultivator comprising a pair of runners, an arched transverse shaft carried on the runners andprovided with a seat, cylindrical rollers journaled on4 the opposite sides of the 'shaft a suitable distance above the runners, standards secured to the forward portions of the runners, a cross-bar secured to the upper ends of the standards, braces secured at their opposite ends to the terminals of the shaft and cross-bar, a brace secured at its opposite ends to the arched portion of the shaft'and the central portion of the crossbar, andcultivating appliances suitably se cured to the rear of the runners, and arranged to follow the rollers, substantially as shown and described.

3. A cultivator comprisinga pair of runners, an arched transverse shaft carried on the runners and provided wi th a seat, cylindrical rollers on the opposite sides of the shaft, standards secured to the forward portions of the runners, foot-'rests thereon, a cross-bar secured to the upper ends of the standard, braces securedy at their opposite -ends'to'vv the terminals of the arched shaft and cross-bar, bearings secured at the rear ends of the runners, a transverse arched shaft journaled therein, a handlever for operating the latter, cultivating appliances secured to the opposite sides of the shaft, and a fender pivorally secured to the rear ends of the runners, substantially as described.

4. A cultivator, comprising a pair of runners, a cross-bar supportedtherefrom, and rollers at opposite sides of the runners and supported at their opposite ends from said runners and cross-bar. Y

5. A cultivator comprising apair of runners, a cross-bar supported therefrom, a shaft rearward of the cross-bar and also supported from the runners, rollers journaled on said shaft outward ofthe runners, and braces connectingthe outer ends of the said shaft with the cross-bar. j

6. A c ultivator, comprising, a pair of ,runners, a cross-bar supported therefrom, rollers at opposite sides of the runners, and supported at their opposite ends from said runners and the cross-bar, and cultivating appliances rearward and rollers.

7. Acnltivator, comprising runners,across bar supported therefrom, ashaft rearwardof the cross-bar and alsosupportedfrom said runners, and provided between the latter with an arch, a brace connecting the cross-bar and arch, and a seat upon the latter.

8. A cnltivator, comprising a pair of run ners', a cross-bar supported therefrom, rollers at opposite Isides of the runners and supported at their opposite ends from said runn the path of said ners and the cross-bar, cultivating appliances rearward and in the path of said rollers, and a fender between said cultivating appliances and behind the runners.

In testimony whereof @I afx my signature in the presence of two witnesses.
